Abstract: An aqueous alkaline suspension of finely divided, X-ray amorphous sodium aluminium silicates with the composition 0.9 to 1.1. Na2O : 1 Al2O3 : 1.8 to 3.6 SiO2 is produced by continuously mixing an aqueous sodium aluminate solution with an aqueous sodium silicate solution in the presence of an excess of soda lye at high temperature. The reaction components are continuously fed into an agitator ball mill suitable for wet crushing, the apparent volume of the balls in which comprises over 50 % of the mill chamber volume, and the average time for which the reaction mixture stays in the mill is set from 3 to 40 s at a temperature of 40 to 80  DEG C.

Title: Spinning machine yarn monitor - shows overlapping signals from service robot during repair of broken end with logic analysis test of equipment
Inventor: LOCHBRONNER HUBERT
IPC: D01H13/16
Filed: 1992-04-16
Abstract: A process to test the yarn presence detector at a spinning position on a frame, where an operation with monitor gives an indication of a change of circumstance. A second monitor briefly overlaps this function, which gives an indication of the result of the test. The detectors may be capacitance of photo-electric. On the frame several positions are connected to a controller. The function may be to determine the quality of yarn as well as to sense absence, when a break occurs. The travelling service robot is aligned to splice a broken end, and it is necessary to utilise a mechanism which withdraws yarn, in order to feed into the rotor of the spinning position, then withdraw it to spin on, and if this is successful, to ensure the winder continues to reel on. ADVANTAGE - The yarn presence detector on a spinning position may be defective as a result of dust on the lense, static electricity, a temperature change, and similar circumstances. Identical equipment on the service robot is arranged to duplicate the informatioation output for a brieft time, and results from both detectors are analysed in the central controller. This prevents any operation which may be deleterious to the spinning equipment.

Abstract: An electro-magnetic control valve (42) has a housing defining valve seats (64, 66), and valve members (68, 70) arranged so as to face the respective valve seats (64, 66). The valve members (68, 70) are formed on a valve rod (67) which is mechanically connected to a solenoid actuator (46). First and second diaphragm members (88, 96) are provided for connecting the valve rod (67) to the housing and for sealing a flow passageway in the housing when the valve rod (67) is axially moved by the solenoid actuator (46). The first diaphragm (88) seals the flow passageway from a chamber (104) inside the solenoid actuator (46). The second diaphragm (96) seals a second chamber (106) from the flow passageway. An axial opening (67-2) is formed in the valve rod (67) for creating a communication passageway connecting the chambers (104, 106) to each other for equalizing the pressure therein. The pressure equalization allows the valve rod (67) to move in response to a small force generated in the solenoid actuator (46).   <IMAGE>
